ADP3605
–3–
REV. 0
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADP3605 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges larger than 600 V HBM.
Therefore, proper ESD precautions are recommended to avoid performance degradation or loss
of functionality.
WARNING!

Positive Terminal for the Pump
Capacitor.
Device Ground.
Negative Terminal for the Pump
Capacitor.
Logic Level Shutdown Pin. Apply a
logic high or connect to V
IN
to shut-
down the device. In shutdown mode,
the charge pump is turned off and
quiescent current is reduced to 2
μ
A
(typical). Apply a logic low or con-
nect to ground for normal operation.
Output Voltage Sense Line. This is
used to improve load regulation by
eliminating IR drop on the high
current carrying output traces. For
normal operation, connect V
SENSE
to
V
OUT
. See Application section for
more detail.

Positive Supply Input Voltage. Con-
nect a low ESR bypass capacitor
between this pin and device ground
to minimize supply transients.
